The purpose of the current study is to determine the opinions of children attending forest kindergarten about the concept of environment. The participants of the study are thirty six 50-70 month-old children attending a forest kindergarten. In line with the purpose of the study, the triangulation design, one of the qualitative research models, was…

Cognitive difficulty arises from two types of cognitive processes: treatments; within the same, conversions; between different types of representational registers. Conversions are difficult since they ask for understanding of two representations. Direction and the choice of first register could be a threshold for the student. Wasan geometry is…

The acquisition of procedural and conceptual knowledge is imperative for the development of problem solving skills in mathematics. However, while there are mixed research findings on the relationship between the two domains of knowledge in some branches of mathematics, the relationship between learners' procedural and conceptual knowledge of…

The purpose of the study focused on analyzing how high school students perceive the topics of money management, savings and investment. For this purpose, it was necessary to use the instrument designed by the National Commission of Retirement Savings Systems (2017) from which the items on money management, savings and investment were taken. The…

Genetics is an area that is increasingly important in people's daily lives. Despite this, its teaching/learning is among the most challenging topics in biology. Several instruments were created over a number of years to ascertain the quality of teaching and learning genetics. In our study, we created a specific instrument to investigate Mendelian…

Research has shown the highest level of understanding in the geosciences to be the ability to think about the Earth as a dynamic system. The Earth system contains four spheres: the geosphere, the hydrosphere, the biosphere, and the atmosphere. These spheres are linked through the biogeochemical cycles that move matter and energy through the…

Many physics projects recently designed for high school teachers use Arduino as the main tool for managing sensors and data acquisition. This is a low-cost integrated development environment programmed with a simplified version of the C++ language. In comparison, the Raspberry Pi 3 platform, which also allows for the design of physics projects,…

This experiment combines analytical techniques of solid-phase extraction (SPE) and gas chromatography quadrupole time-of-flight mass spectrometry (GC-QTOF-MS) to determine organochlorine pesticides (OCPs) in river water as a means to develop and improve student understanding of the use of GC-QTOF-MS for qualitative and quantitative analysis. In…

This work aims to evaluate the evolution of chemical bonding concepts of high school students at public schools in southern Brazil. For this, we built the epistemological profile of each student who took part in a teaching-learning sequence (TLS) about this topic, based on the foundations of Bachelard's theory. Following the principles of the…

Organic electrosynthesis is an increasingly popular tool for driving and probing redox reactions. Recent advances in this field often employ an electrocatalyst to enhance the selectivity and efficiency of electrochemical reactions. A laboratory experiment was developed to introduce students to relevant mechanistic techniques in electrochemistry…

Highly efficient microwave-assisted organic synthesis is now commonplace in both industry and academia. Recently, a conductively heated sealed-vessel reactor was introduced that acts very similarly to a microwave reactor and is more affordable. Application of such reactors in teaching laboratories is advantageous because of the restricted window…

Background/Context: There are recent trends of bringing highly defined, teacher-directed pedagogies into early-childhood contexts in Australia, the United States. and other Western contexts. While the justification for these moves is often the improvement of outcomes for young children, they ignore the large body of research that attests to the…

The primary objective of this study is to review and characterize research-based music assessments that might be used to guide and assist teachers and students in transforming their attitudes and perceptions, ability to express their ideas and concepts during the assessment process openly. This study employed descriptive and autoethnographic…

This research explores how primary school teachers use games to enhance pupils' learning and development of conceptual knowledge. The study employs an illustrative case study design; data was collected through interviews with thirty (30) teachers who were selected using purposive sampling technique. Twenty teachers had some knowledge of game-based…

Presenting novel numbers about climate change to people after they estimate those numbers can shift their attitudes and scientific conceptions. Prior research suggests that such science learning can be supported by encouraging learners to make use of given benchmark information, however there are several other numerical estimation skills that may…
